This innovation ensures that the battery can charge and discharge at higher rates without compromising its longevity. It also contributes to the battery’s ability to maintain performance in extreme temperatures

Explanation and Implications of Advanced LFP Battery Technologies

Granular Gradation Technology

Granular Gradation Technology involves the meticulous positioning of nanoparticles within the cathode material of a battery. By placing each particle in an optimal position, the technology significantly improves the energy density and durability of the battery. This precise arrangement minimizes degradation and ensures uniform performance over many cycles. This is achieved through advanced nanotechnology techniques, which allow for the controlled deposition and organization of particles at the atomic or molecular level. The structured material resulting from this technology facilitates efficient ion transport, thereby enhancing the battery’s overall performance and lifespan.

Atomic Layer Deposition (ALD) in Battery Manufacturing

Atomic Layer Deposition (ALD) is a technique used to apply ultrathin films to various components of a battery, such as electrodes and separators. ALD works by depositing materials one atomic layer at a time through a series of self-limiting chemical reactions. This process allows for precise control over film thickness and composition, which is crucial for enhancing battery performance. For example, ALD can be used to coat lithium iron phosphate (LiFePO4) electrodes with materials like aluminum oxide (Al2O3), which can improve the electrode’s stability, reduce degradation, and enhance the battery’s cycle life.

EVE Lithium LFP Cells List 3.2v

A list of cells manufactured by EVE in July 2024.
It details the capacity, energy density, estimated cycle life, weight, and Internal resistance of each cell.

Using this information you might be able to decide what cells suit your application best.
For example the LF50k cell is rated for 7000 cycles at 1C charge and discharge. But its energy density is very low. The main reason it gets such a good rating is because it can be actively cooled or heated in the right application, which can help tremendously with lifespan.
However you will also note that cycle life is now mostly spoken about at 0.5C or P. Meaning much of the information previously released has been further corrected over time.
All of these numbers are best case scenario, and usually at 25 degrees Celsius. So these numbers are basically unattainable in most cases.

Hithium 280ah 300ah and 320ah cell Lifepo4 Review

Wondering about Hithium Lifepo4 cells quality?

Hithium 280Ah cells are a type of lithium iron phosphate (LiFePO4) battery cells. They are known for their high energy density, long cycle life, and safety features123.

Information about the cell. The cell is identical to the current reference design of a prismatic Lifepo4 cell with the dimensions of 207mm x 173mm x 71mm. These are identical in every way to the cells made by CATL, EVE, CALB, GOTION, BYD, GREAT POWER, REPT, SUNWODA and the list goes on. All of these currently manufacturer this exact same cell, with the exact same dimensions. They all use the same ingredients, with very minute differences to the cathode and anode and electrolyte mixture.

202303301648005656
290AH
Hithium 280AH
  • Product certifications:
    IEC 62619, UL 1973, UL 9540A, UN 38.3
  • Company certifications:
    ISO 9001, ISO 14001, ISO 45001
  • Environmental Compliance: ROHS, REACH

High safety

  • Hithium-developed prismatic LFP cell with high thermal stability
  • Passes crush and nail penetration test
  • Ultra wide operating temperature range


Overall this cell is modified to last longer. Although the truth is the cycle count can be manipulated such as 6000 cycles at 80% is the same as 9000 cycles at 70% and so on. So the claim of 10000 cycles is probably true. Especially considering they are made with the intention of Energy storage, so with a Hithium cell you know you are getting something that will last a very long time.

Origins and Ownership

Envision AESC (Automotive Energy Supply Corporation) is a global battery manufacturer focused on powering electric vehicles (EVs) and energy storage systems.

  • Founded in 2007 in Japan as a joint venture between Nissan, NEC Corporation, and NEC Tokin.
  • In 2018, China’s Envision Group acquired a majority stake. Nissan retained a minority share.
  • Since then, the company has operated as Envision AESC, expanding into one of the world’s fastest-growing battery producers.

Products and Technology

Envision AESC designs lithium-ion battery cells and packs for both cars and stationary energy storage.

  • Chemistries: The company produces both NCM (nickel-cobalt-manganese) and LFP (lithium iron phosphate) cells, depending on the application.
  • EV Batteries: Its Gen5 platform (based on NCM 811 chemistry) targets higher energy densities, approaching ~300 Wh/kg in development.
  • Energy Storage: In 2025, Envision AESC announced 315 Ah and 530 Ah large-format cells, designed for long cycle life (~12,000 cycles) and high efficiency (>95%). Mass production is targeted for 2025.
  • Safety: The company highlights passing over 200 global safety tests, including a CSA-supervised 49-hour fire safety trial. It also claims a record of “zero major safety incidents” in its ESS products.

AESC: 530Ah Battery Cell

Envision AESC has unveiled a 530Ah energy storage cell delivering over 1.6kWh per unit. With 12,000-cycle longevity and 95% energy efficiency, it’s fully compatible with mainstream ESS solutions. Mass production and deliveries are set to begin in 2025.

Global Footprint and Capacity

Envision AESC is aggressively scaling with gigafactories worldwide:

  • Japan: Original facilities supplying early Nissan Leaf batteries.
  • UK (Sunderland): Expanding capacity to support Nissan’s EV hub.
  • France (Douai): A ~9 GWh plant near Renault’s ElectriCity, backed by EU funding.
  • Spain (Navalmoral de la Mata): €1.1 billion LFP factory, with production targeted for 2026.
  • China (Cangzhou, Hebei): “Zero-Carbon Intelligent Industrial Park,” with 10 GWh in production and another 10 GWh under construction.
  • USA: Plants announced in Tennessee and South Carolina; however, the Florence, SC site was paused in June 2025 due to policy and tariff uncertainty.

Past company roadmaps projected hundreds of GWh of global capacity by 2030, but actual targets depend on market conditions and government policy.

Partnerships and Customers

Envision AESC supplies some of the world’s biggest automakers and energy companies:

  • Nissan: Longstanding partner for Leaf and future EV platforms.
  • Renault: Supply through the Douai factory in France.
  • BMW: Planned supply for Spartanburg, USA production.
  • Energy storage integrators: Recent announcements of over 40 GWh of ESS cell supply contracts in China.

Challenges and Risks

Despite its growth, Envision AESC faces several challenges:

  • Policy Risks: Trade disputes and changing subsidy rules (especially in the U.S.) can stall investments.
  • Intense Competition: Rivals such as CATL, BYD, and LG Energy Solution currently dominate global market share.
  • Technology Race: Sodium-ion and solid-state batteries are emerging as future competitors.

Future Outlook

Looking forward, Envision AESC is focused on:

  • Expanding global capacity to the hundreds of GWh scale by 2030.
  • Delivering EV batteries with longer ranges (targets >1,000 km per charge).
  • Scaling grid-scale storage cells for renewable energy and Virtual Power Plant (VPP) projects.
  • Achieving zero-carbon manufacturing across multiple new gigafactories.

Key Takeaways

  • Envision AESC is a Chinese-owned, globally active battery maker with Japanese roots.
  • It is not affiliated with Cornex (a separate Chinese company).
  • The company is rapidly scaling with gigafactories across Europe, Asia, and North America.
  • While facing risks from policy and competition, Envision AESC is positioning itself as a key global player in the EV and ESS battery market.
